Network Gateway For Automotive Ethernet, Classical CAN, And CAN FD
Posted by on
Vector Informatik released its VN5620 network gateway for Automotive Ethernet and Classical CAN, as well as CAN FD networks. The two CAN FD interfaces utilize the TJA1057 transceivers from NXP.
The device is suitable for data analysis, simulation, and testing tasks. The data monitoring per Ethernet warrants a transparent connection between two nodes with a precise timestamp. The precise timestamping is also available for CAN Bus and CAN FD data frames. The two CAN Bus ports can be accessed via the 9-pin D-Sub connectors. LEDs display the activity of the CAN Bus, CAN FD, and the Ethernet network. The hardware configuration options permit the design of existing bus simulations with Vector's CANoe software. This enables the abstraction between networks and network simulators. Furthermore, it is possible to emulate various network topologies.
The device features media conversion functions and a data link between 100 Base-T1 /1000 Base-T1 and the 100 Base-TX /1000 Base-T physical layer. Each CAN Bus and CAN FD port can be accessed individually via the interface. This feature allows the user to test several identical systems on a test bench, to reprogram the ECUs (Electronic Control Unit), and to perform in-vehicle diagnostics. Ethernet (1000 Base-T) or USB 3.0 can be used as an interface to the computer.
The device’s configuration options permit the handling of high data rates. Testing engineers can implement various test scenarios by connecting different segmentation types. Saving functions enable the restoration of device configurations. This function can be activated without a PC connection. The device can be used either as a network interface or as an expansion device for the VN8914, which is a modular interface hardware with channel combinations for Classical CAN, CAN FD, LIN, Flexray, SAE J1708, and K-Line.
The interface dimensions are 143 mm x 153 mm x 37 mm (5.6" x 6" x 1.5"). It can be used at the office and on test benches. The operating temperature (0 °C to +45 °C) and voltage range (10 VDC to 24 VDC) have been designed accordingly for application purposes. Windows 10 is the required operating system.
Automotive Ethernet - The Definitive Guide
Ethernet, the most widely used LAN technology in the world, is taking the automotive world by storm. As the electronic content in cars continues to grow, Ethernet promises to improve performance and enable powerful and useful applications. In its 1,161 pages, Automotive Ethernet – The Definitive Guide explains how Ethernet technology has been adapted via Broadcom's new BroadR-Reach standard to bring Ethernet hardware and applications to vehicles.
Topics covered:
- Automotive electromagnetic, environmental and electrical requirements
- Network fundamentals and the OSI Reference Model
- IEEE Project 802; Ethernet Physical Layer and Media Access Control, including BroadR-Reach, MAC addressing, frame formats and hardware
- A comparison of Ethernet to automotive networks such as CAN, LIN, MOST, and FlexRay; and TCP/IP, including IPv4/IPv6, ICMP, ARP, NAT, TCP, UDP, and DoIP.
